Hot Tub Boat Machine
While the anxiety of waiting for someone to build a hot tub time machine is piling up, this hot tub boat machine will certainly reduce that anxiety by a fraction. Besides being a regular hot tub, this boat actually moves. It can be controlled via the joystick that is mounted right next to the tub (whoever sits the closest gets to control it) and it moves up to 5 mph which is the perfect speed to enjoy the view of the surroundings while in a hot tub. It also has speakers integrated into it which can be connected via Bluetooth and it has four ice chests to store beer and champagne.
